Hamburg Township,

Livingston County, Mich, assignor to Fram Corporation,

a corporation of node Island Application December as, 1944,. Serial No. 510,092 3 Claims. (01.206-56) This invention relates to a package and dis pensing arrangement for filter elements or cartridges used from time to time 'to replace eartridges which have become saturated withcthe sludge or contaminant which the filter is designed to remove from the filtrate which passes through: it. These cartridges are usually supplied in a box, which may rest upon a tablerbench, or other suitable support.

One of the objects of this invention is to provide a package of a plurality of cartridges, one. of which at a time maybe taken from the pack, for use in a filter. l

Another object of the invention is to provide a package of a plurality of cartridges, which may be suspended from above within easy reach of a person desiring to have for use one of the cartridges for placing in a filter. i l

Another object of the invention is to provide a package in which a gasoline gauge may be provided as a usefulpart of the package and which. may serve ass gauge upon exhaustion of the cartridges in the package; 7 Another object oi the invention is to utilize the gasoline gauge of the package as a suspending means. i

Another objectof the invention is to provide a package to have a cover which will exclude dirt from the package. V l

With these and other objects in view, the invention consists of certain novel features of con struction as will be more fully described and pointed out inthe appended claims.

Fig. 1 is a perspective view of the package.

Fig. 2 is a fragmental sectional view.

Fig. 3 is a perspective view of the supporting member or gasoline gauge. l

Fig. 4 is a plan view of the sheet stock wrapper.

In proceeding with this invention. 1 assemble a plurality of cylindrical cartridges, having an axial center opening in a' position so that the axial openings will be in registration or alignment, a gasoline gauge member of rigid construction' is placed through the axial opening of the plurality oi-cartridges and provided with a rcmovable abutment at its lower end and a surpending loop at its upper'end whereby the plurality of cartridges may be suspended in a 'pend ant relation from the rigid member.

provided to extend over the uppermost cartridge with a flange to tightly fit about the uppermost cartridge and a perforation to receive the rigid member. 'A wrapper of sheet material, such'as paper, of a length to extend the entire axial length of the plurality of cartridges, is wrapped about the cartridges so as to hold them as a single .unit. Some indication is marked onthis wrapper to show approximately the line of juncture between the cartridges, and this indication may be in the form of a weakening lin easily ruptured for disconnecting one of the cartridges from the package. This wrapper also affords a surface for printing directions orladvertising matter which may, be desired thereon. With reference to the drawings, I designates a cartridgewhich will be one of a plurality. of cartridges inthe package. It consists of a cylindrical wall ll having end walls I2, 12' with central opening l3, l3 which maybe connected by a center tube M oi the cartridge. cartridge, between the center tube and the cylindrical wall ll, suitable filtering media l may be provided. In some cases cartridges of a different construction may be utilized, the essential part of the cartridgebeing that it have a center opening and some filtering media radially outwardly from this opening. The outside shell H is unimportantfrom the standpoint of the invention here illustrated. The cartridges which are here shown are each equipped with a gasket l6 packaged along the surface of the cartridge in and washers l1. located between the cartridges which may be utilized in positioning the cartrldge in the filter and may of course be assembled in any waywith the cartridges which are provided. p Two mutually cooperative means of assembling the plurality of cartridges in a unit package formation are provided. One of these means is a wrapper of sheet material (see Fig. 4) which I have here illustrated as a sheet of paper of a length equal to substantially the length of the axially assembled cartridges, one in contact with the other. Thewidth of this sheet of material is a this loop at the upper end of A dust cover or cap ma be 60 ening this portion, such little greater than the circumference of scaryea. soas to provide for a portion M to be over apped 'bya portion 22 at the opposite marginal edges, Some sort of cement will be utilized for at- -taching these overlapping portions 2| and 22 so that all of the cartridges will be wrapped by this single sheet of paper. Tightly wrapping the cartridges in this manner serves to hold them inaxial alignment. At the line of juncture between the cartridges I will provide an indicating line 23 to extend circumferentially about the wrapper and which will indicate the axial length of the cartridge or the junction between cartridges. This line 23 may be conveniently formed by weakfor instance as by spaced e which may be.

Within the V perforations. The name of the package may be placed in one of the areas as 24 while other advertising material maybe placed in the areas 25, 26 or 21. Instructions may be placed in the areas 28, 29, 30 and 3|, that the manner of using the package may be given to the person who is to use the same. a a

The other means or" holding the plurality of cartridges in assembled relation is a rigid member 35 which is in the form of a rectangular wooden stick, although any rigid member may be provided. This stick is passed through the center tubes 44 of the assembled cartridges and has a hole 36 at its lower end for the reception of a cotter pin 31 which may be removably positioned in this hole. A washer 38, having an opening 39 of a shape to receive the stick or rigid member 35 is positioned above the cotter pin and forms an abutment upon which the lowermost of the plurality of cartridges rests. Thus, when the stick is suspended, this abutment will serve as a means for holding all of 'the cartridges on a stick in assembled relation. 7 At the upper end of this rigid member another hole 40 is provided, in which there is located a loop 4| of bail like formation so that the package may be-suspended from some book 50 or overhead support.

This rigid member 35 is marked in such a mannerv that it may be used as a reason of graduations 42 provided on opposite sides or its lower portion so that the same may be utilized as a auge. Advertising material may be provided at 43 on the alternate sides of the rectangular member. tral perforation of a size and shape to receive the rigid member 35 is positioned on this rigid member below the loop 4| and has a cylindrical flange 45 to extend down over the wrapper which is positioned about the cartridges. This cover serves as a means for holding the upper edge of the wrapper in wrapped position. and serves to prevent dust from accumulating on the horizontal surface of the upper cartridge. Its squared opening 46 also would assist if the cover were made of sufiiciently heavy material to resist the turning of the upper cartridge by any torsion being applied to the lowermost cartridge for the rupturing of the wrapper about the indicating line 23.

In use, the package will be suspended from some overhead support 50. If it is desired to extract the lowermost cartridge from the package. one hand will be placed upon the cartridge above the lowermost cartridge, nd another hand 4'! upon the lowermost cartridge. A relative twisting motion about the axis of the cartridge as a center will serve to rupture the wrapper along the lowermost line 23 whereby the lowermost cartridge is then free from being bound in assembled position b the wrapper. It is then merely necessary to remove the cotter pin 31 from the hole 36, removing the washer 38 and withdrawing the lowermost cartridge from the rigid member or oil gauge 35. After withdrawing the lowermost cartridge the washer is replaced and the cotter pin replaced, so as to hold the remaining cartridgesin assembled position. which will slide downwardly on the rod 35 to be supported by the washer. The wrapper will be stripped from the cartridge which is removed from the pack, and the cartridge is ready for use. Gaskets I6 and washers I! which are required are assembled with the cartridge for use. If another cartridge is required, the same operation gas gauge by' A cover 44 having a cenwill be again repeated. When the last cartridge is used, the rigid member 35 may be utilized as a gas gauge, which is marked at 42 appropriately for indicating the quantity of gasoline which is in the tank into which it will I claim:
